A computer model of the temporal course of agrammatic sentence understanding: The effects of variation in severity and sentence complexity

In this article, we present SYNCHRON, a computer model of Kolk and van Grunsven's (1985) hypothesis of agrammatic comprehension deficits. According to this hypothesis, parsing fails in agrammatic aphasies since syntactic representational elements that need to be active simultaneously are often not coactive because of disturbances in timing due to brain damage. SYNCHRON has been especially designed to account for two neglected aspects of agrammatic comprehension: degrees of severity and the sentence-complexity effect. We report an attempt to simulate data from two sentence-picture-matching studies in which a qualitatively similar sentence-complexity effect was found at two different average levels of severity. This pattern was reproduced when the timing disorder was assumed to affect syntactic phrasal categories, but not when it was assumed to affect function-word categories. When phrasal categories were involved, fit was not much affected, whether the damage was assumed to slow down the time for an element to be retrieved, or to decrease the time for an element to remain available.     

How slips result in traffic conflicts and accidents

In this study subjects kept diaries about unintentional acts during driving. They were asked to record errors at skill-based level: slips and lapses. They also recorded the circumstances preceding these errors and the consequences for road safety. It was demonstrated how insight into the nature and antecedents of these ‘human errors’ contributes considerably to the understanding of road safety. By focusing on the conditions which control the occurrence of unintentional acts the study shows how these errors or their consequences can be controlled. A relationship was established between the specific conditions that evoke these slips and generic classes of condition that are conducive to errors: latent failure types. It is argued that in conditions controlled by latent failures cognitive processes produce not only skill-based errors but also rule- and knowledge-based errors. It is claimed that strategies to increase safety should be directed at these latent failures, rather than at the errors that follow from them.     

Implicit and explicit attitudes toward fatness and thinness: The role of the internalization of societal standards

Two studies examined restrained and unrestrained eaters’ implicit and explicit attitudes toward fatness and thinness. Participants completed measures of implicit and explicit attitudes toward fatness and thinness (Studies 1 and 2), and a measure of the internalization of sociocultural attitudes toward thinness (Study 2). Restrained and unrestrained eaters both had strong implicit negative attitudes toward fatness, but restrained eaters had stronger negative explicit attitudes and beliefs about fatness. Explicit attitudes and beliefs were related to the degree of internalization of sociocultural attitudes, and the internalization of sociocultural attitudes partially mediated the relation between dietary restraint and explicit attitudes. These results suggest that most people are aware of societal standards regarding fatness and thinness and have developed negative implicit attitudes toward fatness, but that only some people (in particular, restrained eaters) have internalized these standards and developed negative explicit attitudes toward fatness that they endorse as personal beliefs.     

Deficits in acquisition and extinction of conditioned responses in mGluR7 knockout mice

Metabotropic glutamate receptor 7 (mGluR7) is expressed in brain regions implicated in emotional learning and working memory, and previous behavioral experiments indicated contributions of mGluR7 to various complex behaviors. In the present study, we investigated the specific effects of mGluR7 deletion on a variety of conditioning paradigms that model crucial neurocognitive and psychopathological behavioral phenomena. Null-mutant mGluR7^−/− mice displayed defects during scheduled appetitive conditioning, acquisition and extinction of appetitive odor conditioning, extinction of response suppression-based conditioned emotional responding (CER), acquisition of discriminative CER, and contextual fear conditioning. mGluR7^−/− animals were slower to acquire the association between a conditioned stimulus and a positive or negative reinforcer, but eventually reached similar performance levels to their wildtype littermates. Notably, extinction learning of conditioned responses was slower in mGluR7^−/− compared to wildtype animals. The observed delays in the acquisition of complicated stimulus associations across conditioning procedures may suggest a critical role for mGluR7 in neurocognitive functions and psychopathology.     

Health and human services for persons who stutter and education of logopedists in East-European countries

The International Association of Logopedics and Phoniatrics (IALP) assessed the therapy status of fluency disorders, service opportunities, and education of logopedists (speech-language pathologists) with a mail survey in Eastern Europe. Information was collected on the following aspects: incidence, prevalence, availability of information, non-therapeutic support for persons who stutter (PWS), providers of diagnostics and therapy, cooperating professionals, therapy approaches, forms, goals, financing, early detection and prevention, training of professionals, specialization in stuttering therapy, needs for improving the situation of PWS, and problems which hinder better care. Stuttering therapy for children is available in many countries and is frequently provided by the educational system. Therapy for adults is provided best by the health services but is not satisfactorily available everywhere. Modern therapeutic approaches coexist with obsolete ones. Lack of resources, awareness, entitlement, and assessment of therapy effectiveness are pervasive problems.

Educational objectives: Readers will be able to describe and evaluate: (1) the therapy status of fluency disorders and service opportunities in various East-European countries; (2) the training of logopedists (speech-language pathologists); (3) specialization in stuttering therapy; and (4) the organizational services for PWS within the health and human service systems.     

Attitudes of Potential Providers Towards Preconceptional Cystic Fibrosis Carrier Screening

To determine the attitudes of potential providers (general practitioners and Community Health Service workers) towards preconceptual cystic fibrosis (CF) carrier screening and to determine which factors are associated with a positive attitude. A survey was conducted among 200 general practitioners (GPs) and 134 Community Health Service (CHS) workers. Fifty-two percent of the eligible GPs participated and 84% of the CHS workers. Fifty-five percent of the GPs and 73% of the CHS workers had a positive attitude towards routinely offering CF carrier screening, and more than 80% were in favor of informing the target population about the possibility of having a CF carrier test. A positive attitude was associated with (a) high perceived severity of CF, (b) religion (nonreligious compared to Reformed), (c) low perceived barriers, and (d) high perceived test reliability. The care providers who are most likely to be involved in a preconceptual CF carrier screening program, i.e. GPs and CHS workers, generally have a positive attitude towards the implementation of such a program.     

The problem of polytheisms: a serious challenge to theism

Theistic and analytic philosophers of religion typically privilege classical theism and monotheism by ignoring or underestimating the great threat of polytheism (We take ‘theism’ to mean ‘classical theism’, which is but one of many possible monotheisms. Avoiding much of the discussion around classical theism, we wish to focus on the challenges in arguing for monotheism over polytheism. We take monotheisms and polytheisms to be versions of supernaturalism, and not of ‘theism’. We consider monotheisms and polytheisms to entail the notion of divine transcendence). We develop an argument from infinitely many alternatives, which decisively demonstrates that if a monotheistic or polytheistic god-model obtains, it will almost certainly be polytheistic. Probabilistic calculations are performed in order to illustrate the difficulties faced by the monotheistic proponent. After considering possible objections, such as whether there should be limits placed on how many possible god-models could obtain, we conclude that our argument from infinitely many alternatives is sound, and highly unlikely to be overcome.     

Self-reported overeating and attributions for food intake

Objective: We examined whether people’s attributions for their eating behaviour differ according to whether they believe they have eaten more, less or about the same as they normally would.

Design: Participants were served a small or large portion of pasta for lunch. Afterwards, they were asked to compare how much they ate in the study to how much they normally eat for lunch, resulting in three intake-evaluation categories: ‘ate less’, ‘ate about the same’ or ‘ate more’.

Main outcome measures: How much participants ate; the extent to which they attributed their food intake to an internal cue (i.e. hunger) and an external cue (i.e. the amount of food served).

Results: Participants served a large portion ate more than those served a small portion, but the magnitude of the portion-size effect did not vary across intake-evaluation categories. Furthermore, although participants in all groups indicated that their hunger influenced how much they ate, only those in the ‘ate more’ group indicated that the amount of food available influenced how much they ate.

Conclusion: People appear to be willing to explain their food intake in terms of an external cue only when they believe that they have eaten more than they normally would.
